Hi
I have a 2004 Dodge Ram 4X4, with 5.7 Hemi engine. I have been trying to get the computer tuned for use with a hydrogen fuel cell. The fuel cell is about 2L per minute output. I have installed a digital EFIE for 02 Sensor Basics. The O2 offset is set at 187.8 MV now. We have been trying to adjust it from a 150 to 250 MV Range. The Coolant Temp is 190 Deg. The AIT is set at 176 Deg. I am looking for someone who had had some experiance with a 2004 and Hydrogen and tuning the computer to accept it. There are so many suggestions which I think we have tried most, and I would just like to get this working. Thanks all, and if Anyone has any suggestions, please contact me at bgoinssr@bellsouth.net, and also the info would be good to post here for others. Thanks

 

there is not really any confirmed evidence that this works. you might be barking up the wrong tree if you are looking for an MPG increase.

 

Are you talking about those stupid mason jar kits that supposedly give you 300% increase in MPG? Total waste of time, cut your losses now, they don't work at all not even 1 mpg increase.

 

buy a prius if you want good fuel economy

 

http://www.youtube.com/watch?v=JXK63kvUi6U A buddy of mine had one of these, he got 52mpg, he sold it when gas was $4.50/gal for 4K more than he bought it for 3 months prior.

 

I'm looking into an old TDI jetta right now. i love diesels, but i don't particularly like volkswagon.

 

Wasn't there a full 6 page thread devoted to this topic last summer around this time as well?

 

we had a huge fallout over this about 2 years ago on here. Someone actually made one, swore they got like 1-2 MPG increase.

Turns out he had switched to Premium and only went by the overhead. Those things are crap, wish they actually worked though. On a more serious note, did any of you see the Dateline about it? They are actually prosecuting the companies that sell these kits, they had expert mechanics car engineers and so forth all try to make it work and it actually had a lower MPG and HP on the dyno after install

 

Volkswagon is 30% owned by porsche, what's not to like about that? At least it's a stable company for now.

 

ha, a porsche would be nice. feels a bit like a yuppy car. and resale is too damn hi, so a good used one is a bunch more than comparable cars. i wish more comapnies made entry level diesels.
